Synthesis and evaluation of phenyl substituted sydnones as potential DPPH-radical scavengers

A series of phenyl substituted sydnones has been synthesized and their radical-scavenging activity has been studied on DPPH free radical. Out of eighteen compounds screened, nine compounds show interesting activity. A mechanism is presented whereby sydnones scavenge DPPH radical through donating H-atom at 4th-position. Its strong radical-scavenging activity mainly arises from 1, 2, 3-oxadiazolium-5-olate ring. Different substituents and their positions on the phenyl ring differently influence DPPH scavenging activity and therefore, may provide clues to design and develop better free-radical scavenging sydnones with multiple activities.

One-pot conversion of N-arylglycines to sydnones efficiently promoted by bis-chlorine-1,4-diazabicyclo[2.2.2]octane complex Cl2-dabco in the presence of NaNO2/Ac2O under neutral condition

Bis-chlorine-1,4-diazabicyclo[2.2.2]octane complex, (Cl2-DABCO), has been found as an active chlorine complex for effective one-pot conversion of various N-arylglycines to sydnones in high yields (85-95%) under mild and neutral condition.

Microwave-assisted synthesis of N-arylglycines: Improvement of sydnone synthesis

Reactions of anilines with ethyl bromoacetate under microwave irradiation have afforded N-arylglycines that are subsequently converted to their N-nitroso derivatives with a combination of silica chloride or periodic acid, wet SiO2 and sodium nitrite in CH2Cl2 with satisfactory yields. In the final step, the use of 1,3-dibromo-5,5-dimethylhydantoin (DBH) as a new and effective reagent for dehydration of N-nitroso-N-arylglycines to sydnones was successfully examined.
